That’s what I initially thought, but I could see it being cheaper for the railway company to build solar for themselves. They get the power at cost, and can build a system that can handle lower uptime/greater availability, with storage etc, so that they can avoid paying to upkeep high availability power. I don’t know though. I assume someone with a really nice spreadsheet has looked at this before deciding to pay to build all this.
